Jay Kreps commented on KAFKA-1836:
----------------------------------
Looks like Metadata.awaitUpdate() always calls Object.wait(maxWaitMs) even if
maxWaitMs is 0. Unfortunately Object.wait(0) doesn't mean wait for zero ms, it
means wait forever. So it should be an easy fix--we need an if statement here
to check for a wait time of 0.
> metadata.fetch.timeout.ms set to zero blocks forever

> You can easily work around this by setting the timeout value to 1ms, but 0ms
> should mean 0ms or at least have the behavior documented.
